There's some single stage stuff on the market at $35.00 a gallon..........

As far as the price on a paint job, depends on how much work the car needs, and the quality of finish desired like Hotrodpaint said.

The price of materials and labor both keep going up. For a body shop, just the cost of keeping up with the laws governing them is a huge expense. Quality work at cheap prices is pretty much a thing of the past.
